the PC it appears as a virtual com port to software on the computer. No additional drivers

RX and TX LEDs will flash when data is being transmitted via USB-to-serial chip and

USB connection to the computer (not for serial communication on pins 0 and 1).

As it comes to programming Arduino Uno can be programmed with software

provided. The board is preburned with bootloader that allows to upload new code to it

directly via USB, no external hardware programmer needed. It communicates using

STK500 protocol. If needed, it is also possible to bypass bootloader using the ICSP (In-

Circuit Serial Programming) header.

Very important thing is the USB overcurrent protection in which board is equipped.

connection is automatically broken if more than 500 mA is applied. After removing short

or overload connection goes back to normal.
